Update the DNS plug-in to use Alpine 3.19. To update the builder to Alpine 3.19, we have to update to a newer Go version. Also update to the latest version of the CoreDNS 1.8.x line, which is 1.8.7. The update requires some smaller adjustments in the plug-in imports.
The Dockerfile used to have Windows line endings, this PR also changes this to Unix file endings. That causes the whole file to appear changed.
